How do I load image from Django REST API?
So as stated, I'm having trouble loading images from Django backend(fetch works fine). I've looked other similar questions, but NONE OF THEM HELPED, sadly. So here's my Django code: settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') urls.py from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), ] urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) model.py class Content(models.Model): objects = models.Manager() image = models.ImageField(upload_to='None', height_field=None, width_field=None, max_length=None, null=True, blank=True) key_line = models.CharField(max_length = 100, null=True) ### All 페이지에 보여지는 핵심 문장 body = models.TextField(blank=True, null=True) ### 발췌 내용 I've uploaded an image named 'eeee.PNG', and I can see the data serialized in JSON format like below: [ { "id": 5, "image": "/media/None/eeee.PNG", "key_line": "key.", "body": "blablabla", }, ] And my React code (fetch has been successfully worked) : <Container classname=""> <Row className=""> <Col className="text-text img-eachcake">{this.props.image}</Col> <Col className="text-text img-eachcake" src={this.porps.image}></Col> </Row> </Container> As you can see, I've tried two ways but none of them worked. What do you think is the problem? All the other props are loaded fine. It's just the image file that doesn't work. +in the inspection mode > Elements, I see the line as : <div src="/media/None/eeee.PNG" class="text-text img-eachcake col"></div> -
Pagination feature not working and paginator bar styling is off
I have two bugs in my code, First bug is a styling bug or frontend bug, Second bug is Pagination not working. The second bug is I'm trying to make the button active depending on what page it is, The button only lights up for page 1, When I go to page 2 the button is still active or lit up. The first bug for styling is the buttons were meant to look like this: but they look like this: Current code: <div class="row"> <div class="col-md-12"> {% if listings.has_other_pages %} <ul class="pagination"> {% if listings.has_previous %} <li class="page-item"> <a href="?page={{listings.previous_page_number}}" class="page-link">&laquo;</a> </li> {% else %} <li class="page-item disabled"> <a class="page-link">&laquo;</a> </li> {% endif %} </ul> {% endif %} {% for i in listings.paginator.page_range %} {% if listings.number == i %} <li class="page-item active"> <a class="page-link page-item">{{ i }}</a> </li> {% else %} <li class="page-item"> <a href="?page{{i}}" class="page-link">{{i}}</a> </li> {% endif %} {% endfor %} </div> </div> Intended to look code <div class="row"> <div class="col-md-12"> <ul class="pagination"> <li class="page-item disabled"> <a class="page-link" href="#">&laquo;</a> </li> <li class="page-item active"> <a class="page-link" href="#">1</a> </li> <li class="page-item"> <a class="page-link" href="#">2</a> </li> <li class="page-item"> <a class="page-link" href="#">3</a> </li> <li class="page-item"> <a class="page-link" href="#">&raquo;</a> </li> </ul> </div> … -
How to temporary store a generated image for download
I have written some code for taking an image, and adding some text to it. Currently it just saves the file locally, but I would like it to store the new generated image temporary, so when the session is closed the file is deleted. Also, so in the future multiple users would be able to use the function at the same time, without one user owerwriting another ones image. My current code is: def Output(request): inputValue = request.GET.get('t', '') my_image = Image.open(os.path.join(BASE_DIR, 'media', 'blank.jpg')) title_font = ImageFont.truetype(os.path.join(BASE_DIR, 'homepage', 'static', 'homepage', 'Mistral.ttf'), 60) title_text = inputValue image_editable = ImageDraw.Draw(my_image) image_editable.text((45,333), title_text, (0, 0, 0), font=title_font) my_image.save(os.path.join(BASE_DIR, 'media', 'result.jpg')) return TemplateResponse(request, 'homepage/output.html', {'title': 'Output'}) so instead os saving the image locally as result.jpg, how do I save it temporary for a specific session? -

I am trying to avoid duplicate email in my website form .

Why in an AllowAny view of Django I get 401 Unauthorized using Firefox but not using Edge or Postman?
I'm using knox LoginView to make the login of my backend. This is the code of the view: class Login(LoginView): permission_classes = (AllowAny,) def post(self, request, format=None): serializer = AuthTokenSerializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.validated_data['user'] login(request, user) return super(Login, self).post(request, format=None) When I execute my frontend (developed with angular) and try to login using Microsoft Edge everything works fine. I get the token and save it in local. Same result if I execute a POST using Postman. But, If I try to do the same using Firefox I receive 401 Unauthorized with this JSON: {"detail":"Invalid token."} Why does it ask for a token if its an AllowAny view? Why does it work in Edge and Postman but not in Firefox? More data: This is the authentication class in settings.py: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'knox.auth.TokenAuthentication', ), } EDIT: Actually, it works usign Firefox Developer Edition. -
Triggers are not being created in django-transitions
I am trying to build a basic implementation of django-transitions following the example here. It seems to me that I did everything in line with the example. When I create an instance of my model, however (and even of just the defined mixin itself), there are no triggers. I'm at a loss at what I may have done wrong and why that leads to triggers not being created. Can anyone confirm/help? Here is my workflow definition (lifecycles.py): from django_transitions.workflow import StatusBase, StateMachineMixinBase from transitions import Machine class ContactLifecycleStatus(StatusBase): # Define states ACTIVE = "ACTIVE" INACTIVE = "INACTIVE" BLOCKED = "BLOCKED" # Define human-readable labels for states # TODO: translate labels STATE_CHOICES = ( (ACTIVE, "active"), (INACTIVE, "inactive"), (BLOCKED, "blocked"), ) # Define transitions as constants ACTIVATE = "activate" DEACTIVATE = "deactivate" BLOCK = "block" UNBLOCK = "unblock" # Define human-readable label and css class for use in Django admin # TODO: translate labels TRANSITION_LABELS = { ACTIVATE: {'label': 'Activate', 'cssclass': 'default'}, DEACTIVATE: {'label': 'Deactivate'}, BLOCK: {'label': 'Block', 'cssclass': 'deletelink'}, UNBLOCK: {'label': 'Unblock', 'cssclass': 'default'}, } # define collection of states for machine SM_STATES = [ACTIVE, INACTIVE, BLOCKED,] # define initial state for machine SM_INITIAL_STATE = ACTIVE # define transitions as … -
Django - how do create a model right after User creating form?
So I'm working on this school managing system and I would like to make a signup form, that not only create User, but also create an object with one-to-one link to user.

Django ModuleNotFoundError: No module named 'asgiref'
I have a Django service we are trying to schedule in conjunction with the main application that runs periodically to send automated emails via a batch script. The Django application itself starts up fine, but when I try running the batch script, I get the following traceback: Traceback (most recent call last): File "C:\Program Files\compuweather\compuweather\webapp\management\commands\send_all_clients.py", line 2, in <module> from django.core.management.base import BaseCommand File "C:\ProgramData\Anaconda3\lib\site-packages\django-3.2- py3.8.egg\django\core\management\__init__.py", line 13, in <module> from django.apps import apps File "C:\ProgramData\Anaconda3\lib\site-packages\django-3.2-py3.8.egg\django\apps\__init__.py", line 1, in <module> from .config import AppConfig File "C:\ProgramData\Anaconda3\lib\site-packages\django-3.2-py3.8.egg\django\apps\config.py", line 7, in <module> from django.utils.deprecation import RemovedInDjango41Warning File "C:\ProgramData\Anaconda3\lib\site-packages\django-3.2-py3.8.egg\django\utils\deprecation.py", line 5, in <module> from asgiref.sync import sync_to_async ModuleNotFoundError: No module named asgiref I find that odd considering I have the batch file set to run from an anaconda environment that has Asgiref installed. I can verify this with pip freeze. Here are the versions of the packages I'm using: asgiref==3.3.1 Django==3.1.6 I saw a similar issue here, that was due to the Django and asgiref packages being outdated. I've tried updating both asgiref and Django to the latest versions (those listed), but that also didn't help. My best guess after looking through the traceback is either something is trying to use a deprecated … -

Django for loop only catching the last iteration on button click
I am building a Django movie app which makes use of the TMDB API. The way I have it set up currently is that I have a function in my main.js which is run when the page is loaded which makes the call to the API based on which media_id is clicked from the search results, which saves to local storage. This works fine in this regard. I implemented a review functionality where logged in users are able to leave reviews on whichever title they wish and it saves to the DB, and then on the user account page I have a list displayed of all the reviews a logged in user has left. Up till here everything works as intended but this is where my error lies. Next to each review in the users account page I have a button I want to take the user to the page in which they left the review, however I can only seem to get it to link me to the final title in the list of reviews. The code I have in my account.html file is as follows: <tbody> {% for review in reviews %} <script type="text/javascript"> function resetValues() { localStorage.setItem('movieId', … -

Django-Run a function in the background forever
In my case,I need to process something in the background indefinitely and as often as possible. Tools like Celery,RQ,etc have minimum limit as 1 second to run something periodically.

django url parameter creating in the process
I have no idea how to solve this problem: I have a django webshop project. At the end of the order I would like to redirect the user to a new page about the confirmation. urls.py: `path('confirmation/<str:order_id>/', views.confirmation,` name="confirmation"), views.py: def confirmation(request, order_id): items = OrderItem.objects.filter(order__id = order_id) context = {'items':items} return render(request, 'store/pages/confirmation.html', context) I have a javascript part another view where I do a POST method. If it is successfully done I would like to navigate to the confirmation page. In the data I get back the order_id. var url = '/process_order/' fetch(url,{ method: 'POST', headers: { 'Content-Type':'application/json', 'X-CSRFToken':csrftoken, }, body: JSON.stringify({'myForm':myFormData}) }) .then((response) => response.json()) .then((data) => { window.location.href = "{% url 'confirmation' data %}" }) I guess the problem is that in the very beginning of the execution there is no value of the data, because it is creating in the process. So the view can not render because of the parameter. (But my problem is that the order_id is creating after the POST method). (The Exception Value: Reverse for 'confirmation' with arguments '('',)' not found. 1 pattern(s) tried: ['confirmation/(?P<order_id>[^/]+)/$'] ) What would be the good solution of this situation? -

Django how make makemigrations and migrate when making changes at models
Whenever I make changes to the models (and subsequently to the views) when I do makemigrations or migration, I always run into problems. Sometimes running makemigrations django notices the changes, but then when I run the command migrate django writes that there are no changes to be made. Other times, dozens of exceptions are generated during makemigrations. Django writes that he does not find certain tables or certain fields but I read that the errors report the names before my changes. The only solution to all this is to delete content of: _pycache_ views.py sql3.db3 database Leave only models.py. At this point I can proceed with the makemigrations and migrate commands. The question: is there an easier way? What am I wrong? -
Event handlers fires multiple times when triggered [duplicate]
For some reasons unbeknownst to me, the events for elements I created dynamically fires multiple times (mulitplying itself by three each time). Those, I added manually fire only ones. As you can see, I have some console.log() which I use to track if the function was called multiple times or it was the event handler that fired multiple times.
